Some scientists think that are intelligent life forms on other planets and messages should be sent to contact them. Other scientists think it is a bad idea and would be dangerous. Discuss both the views and give your opinion.

Extraterrestrials, that may range from single-celled organisms to beings with a
civilization
far more advanced than humanity may exist on other planets of the universe. Scientists do not have any evidence to prove their existence to date. According to one camp of scientists, messages should be sent to those aliens to confirm their existence;
however
, the other camp expresses concerns about hailing the attention of alien civilizations. I would delve into both the views in
this
essay. Due of over exploitation, the earth is slowly becoming uninhabitable,
to begin
with. In the true spirit of exploration, astrologists want to explore the space for the existence of advanced
life
forms which would be beneficial for us in the future. Cosmologists like Stephen hawking consider
this
advancement in the
search
of intelligent lives may get to a period in our future where we outgrow our evolutionary baggage.
Furthermore
, a
search
of extraterrestrial civilizations will make us not only technologically more proficient than we are, but more aware of the rarity and preciousness of
life
in the cosmos.
On the other hand
, there is a plethora of risks in contacting extraterrestrial scientists currently have no idea what alien
life
-forms might look like, or how they might respond to contact from human
civilization
. 
Such
advanced aliens would perhaps become nomads, looking to conquer and colonize whatever planets they could reach. We don't know much about aliens, but we know about humans. If we look at history, contact between humans and less intelligent organisms have often been violent and have gone badly for the less advanced. A
civilization
reading one of our messages could be billions of years ahead of us. If so, they will be vastly more powerful, and may not see us as any more valuable than we see bacteria. In conclusion, even though I fear that an advanced alien
civilization
would have no problem wiping out the human race, the desire for the
search
for
life
beyond earth outgrows the risks and I strongly agree that it would give us a commitment to live. We are alive. We are intelligent. We must
search
for the signs of
life
in
this
universe.
